To all whom it mag concern."

Be it known that I, HERBERT Len SMt'Jji-i, a citizen of the United States. rcsidingH-at Los Angeles, in the county of Los Angel-es and State of California, have invented new and useful Improvements in Reinforced; Concrete Sectional Sea-'Walls, of which the following is a specification.

My invention relates" to reinforced con crete sectional sea-walls adapted for placement along bays, inlets and other arms of the sea where the water is comparatively calm and free from storms, and which is designed to replace the usual 'form of wooden retaining walls. bulkheads and like structures erected in salt water for various and aspecial object thereof is to provide a sectional structure that may be readily transportedto the place of use. and which will when erected withstand the desn'ch as the teredo. I I

Another, object is to provide a reinforced concrete retaining wallcomp'osed of a number of sections so united as to form when in place a single unitary structure of great strength, capable of withstandii ig'tlie ravages of the elements and the un'to'ward in- In the accom ilislnnent of theabore ob jects I refera 1y employ a. plurality of trussed uttresses or anchorages, between which reinforced concrete filler or backing plates are secured, the whole mass being held in place by an earth backing.

In the drawings hereto annexed and forming a part of't his specification: Figure 1-.- is a perspective view of my improved wall erected along the embankment being broken away for clarity of illustration. Fig. 2 is a side elevation of one of the buttresses in position. Fig. 3- is a rear elevation of a portionpf the wall, the filler plates being inposltlon and some of them partly close their reinforcement. elevation of the upper portion of my improved wall showing a attached thereto. Fig. 5 1s a plan view of the wall withthe fender and wharf in place thereon. Fig. 6 is a sectional plan now of myimproved sea-Wall. Fig. 7- IS a detail side elevation of one of the buttresses,-

l is a perspective view of another modified form of buttress constru'ctioln- Referring more particularly to the drawings, 10 designates aplu iality of buttresses preferably formed of concrete properly reinforced and of an angular configuration. As all of the buttresses are of the same con- ,will describe only one. As heretofore mentioned the buttress is of an angular truss-ed configuration preferably formed of. steel reinforcing bars 11 0 suitable size and strength which are temporarily tied together preparatory to inserti-on'in the concrete mold forms (not shown). The outer vertical face or um 12 of the buttress is preferably forlnet with a plurality of rods 13, as clearly shown in Figs. 6 and 7 of the drawings which extends below the base 15 of the buttress structure, so that when the buttress is erected in place it will be rigidly maintained against movement. Base 15 of the but-tress extends beyond each side, and bracing ribs 16 extend upward therefrom at an angle to the lowermost series of cross bars 17, thus insurin to the structure.

ture reinforcing rods have been properly tied the water front, portions of broken away totlis- Fig. 4*- is a s lde fender and wharf together the whole skeleton structure "is' thereon, a sufficient time being allowed for the concrete to thoroughly set when the buttress is ready for transportation to its place of'use. hen lacing'the buttresses in position a hydrau ic' jet .is preferably applied to the pier 12 so that it will sink until the base 15 contacts with the bottom. {The inner vertical face of pier 12 is provided. on each side thereof with a vertically extending groove 18, against which the concrete filler or backing plates 20 are adapted to contact. These plates are preferably formed of concrete and are rovide witha reinforcing gtidQl which is formed of horizontally ex- ,tending and vertically disposed steel bars, by means of which the mass of concrete forming the plate is tied together. These lates 20 are preferably placed end on end etween adjacent buttresses to the height of the buttress and are held temporarily in place by means of metallic fingers or arms 22, one end of which is secured to the late. A's fast ,as a section of wall is complete the "space to the rear of the wall is lled with earth fromdredges operating in front, so

that when the wall is finally completed it strength and stability: After the buttress strucuno.

" struction and also for the sake of brevity I placed in suitable molds and concrete poured willform a. structure of reat strength and rigidity, the bases of the uttresses furnishmg a secure anchorage for the walls. By this novel means of construction it is possible to easily erect a wall in a depth of water that would ermit the landiiig of ships of considerablla tbnna e, and at the same time it would afior a convenient means of reclaiming large areas of land covered by shoal water.

In Fig. 8 I'have illustrated another form .of buttress construction in which the round reinforcing bars are dispensed with and in lieu thereof I have substituted a construction in which angle irons 23 are boltedor otherwise secured to plates 24, the concrete being cast around the skeleton structure thus formed as in the preferred form.

In Fi 9 of the drawin s I have illustrated still another form 0 wall construe: tion' in which the concrete plates 20 and buttresses are dispensed with, the wall being formed of monolithic reinforced slabs 25 provided with bases 26 and webs 27, both being reinforced similar to the plate construction. In this construction the slabs are tongued and grooved on their vertical edges, thus forming a continuous wall, the portion 28 of the slabs entering the bottom similar to the lower ends of the piers 12 in the preferred form.

In Fi 4 and 5 I have illustrated a combinedw arf fender construction for the purse of affording a convenient landing place l st vessels, furnishing at the sam e time" a protective fender and preventing myury to the sea-wall. In this construction piles 30 are driven or jetted into the bottom in the usual manner directly in front of the wall. The. wall top in this instance is furnished with a concrete curbing 31, a slmxlarcurbing or footing 32 being laid directly intthe rear and parallel with the curb 31, eachbein rovided with wooden plates 3:3, upon w no the stringers or rafters 34 which support the flooring 35 are laid.

It will be observed from the foregoing de- 'scription that I have provided a novel construction whereby I am enabled to erect a practically indestructible sea-wall in a minimum length of time and in an economical manner.

Having described my invention what I clann as new and desire to secure by Letters Patent is 1. In a concrete retaining wall construction, a plurality of concrete buttresses and a reinforcing means embedded therein, a plurality of concrete plates mounted between said buttresses, each plate being provided with a reinforcement and adapted to form with said buttresses acontinuousvwall, and means formed onthe buttresses for retaining the wall so formed in position.

2. In a concrete retaining wall construction, a plurality of concrete buttresses spaced apart and a reinforcing means embedded therein, and a. reinforced concrete plate between each two adjacent buttresses, said plates and buttresses adapted when placed together to form a continuous retaining wall construction.

3. In a concrete retaining wall construction, a plurality of trussed buttresses formed of concrete and a plurality of metallic reinforcing rods therefor, said buttresses spaced apart, and a plurality of concrete plates with a reinforcing means embedded therein, said plates adapted to form with said buttresses a continuous wall.

4. In. a concrete wall construction, a plurality of triangular supports spaced apart, a plurality 0 plates mounted therebetween, means ormed on said supports to prevent an outward movement of said plates, and means formed on the bases of said supports, whereby they may be rigidly maintained in position.

In witness that I claim the foregoing I have hereunto subscribed my name this 14 day of January, 1909.
